There are a few menu bar apps to open screen sharing, but I wanted one that showed the correct machine icon for each Mac, as a visual cue... so I wrote one :-)

I had some spare parts left over from another app I'm working on, so if this is useful to you, it's free, just for you :-)
Available here: Downloads

It's code signed but not sandboxed (it just doesn't work as well if it is).

It has a boring name and it has no icon, feel free to suggest something :-)

It looks like this - Belgian beer names below being a couple of my Macs :-)
